Did Brian Cox blew it?
« on: July 22, 2012, 05:08:06 PM »
A video by Brian Cox is making the rounds:
<a href="http://www.youtube.com/v/Mn4I-f34cTI" target="_blank" class="new_win">http://www.youtube.com/v/Mn4I-f34cTI</a>

It's part of a lecture series he did for the BBC (I think) called A Night with the Stars. It seems the blew it with his interpretation of the exclusion principle and somehow confused it with quantum entanglement of something like it.
Sean Carroll has a cool (and long) blogpost that explains why he's wrong and how he could've been right.

I would love to have Ben explaining this with some weird analogy.

A bit late to the party, but I've seen this story circulated recently (this week). Pretty disappointing actually, as a science communicator he should endeavour to ensure he's using the correct terminology.

Oh yeah, pauli.

we talk about the exclusion principle a little in the shows on superfluids, neutron stars, superconductors and the dirac sea.

It's hard to explain. I think i put it in terms of bees.
"no two fermions can be in the same location and have the same quantum numbers"

yeah.
it's a fun show idea, but i'll mull over how we can give it a sexy hook.
Titanium Physicists has a pro-bee-analogy agenda. That's certainly no secret.

I remember reading something to that effect in his (co-authored) book The Quantum Universe. It did indeed hinge on the exclusion principle, and the conclusion was something to the effect that every particle is theoretically dependent on every other particle of the same type in the Universe due to this principle, but that the effects are noticeable only at microscopic distances. If I remember correctly... which I probably don't :P
Did I do, O CROM, did I as I said Id do? Good! I did.
